JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 673.620. dated May 7, 1901.

Apnlieation filed May 7, 1900. Serial No.1t'n'784v (No model.)

To tZZ whom, it may concern.-

Be it known that I, GEORGE S. MARSHALL, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have inven ted a certain new and useful Improvement in Journal-Boxes, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is an elevational View of my improved journal-box lid. Fig. 2 is a side elevational view of the same mounted upon the journal-box. Fig. 3 is a similar view showing the lid partially open. Fig. 4 is a sectional view on line 4 4, Fig. l. Fig. 5 is a sectional View on line 5 Fig. 1; and Fig. 6 isa sectional view on line 6 6, Fig. l.

This invention relates to a new and useful improvement in a lid for journal-boxes, such as are usually employed on car-trucks, one object beingtoprovidealid for journal-boxes which when closed will tightly seal the opening in the journal-box, said lid being held in its closed or sealed position against accidental displacement. j

Another object is to make the lid semi-automatic in its opening movement, so that when the lid is raised ashort distance from its seat it will have a tendency to move outwardly and expose the opening in the box.

With these objects in view the invention consists in the construction, arrangement, and combination of the several parts, al1 as will hereinafter be described and afterward pointed out in the claims.

In the drawings, A indicates a portion of the journal-box, which is provided with the usual opening in its outer end, said box also having the upwardly and outwardly extending hinge-lugoJ on its upper face, which hingelug carries the pintle a', forming a pivot for the lid. This hinge-lug is preferably arranged centrally with respect to the box, and the pintle extends on each side thereof. The hingelug is also formed with inclined faces a2 and a3 and a horizontal face a, formed on its upper portion, for cooperating with the lidspring, hereinafter described. The box is provided with laterally-extending flanges a4, which, as shown in Fig. l, (see also Figs. 4 and 5,) are made narrow at their upper ends, hile said flanges diverge at their lower ends, forming a seat of considerable area, against which the inner face of the lid seats itself. The bottom wall of the box curves upwardly and outwardly to form the throat, while said wall at the mouth or opening of the box is preferably inclined, as shown at (t5, Fig. 6.

B indicates my improved lid as an entirety, which is provided with a housing Z) to inclose the hinge -lug and also accommodate the spring C, which cooperates with the inclined faces of said hinge-lug. Lid B is also provided with laterally-extended bearings b' for receiving the pintle a', said bearings, as shown in Figs. 2 and 3, being elongated substantially in the line of inclination of the plane of the flanges a4, while said openings are enlarged at their lower ends to permit the lid to bodily move forward in its opening movement.

b2 indicates inturned flanges which converge toward each other at their upper ends to correspond with the angle of inclination of the flanges a4 on the box.

b3 indicates a flange or rib arranged on the inner face of the lid, near the lower edge thereof, for coperating with the bottom wall of the box, said flange serving as a hood therefor.

An extension b4 lis preferably provided at the lower edge of the lid, by which said lid may be manipulated.

As shown in Fig. 1, the lid is closed, the spring C, bearing against the inclined face a3, tending to force the lid downwardly, wedging the same tightly over the iiauges a4. Should it be desired to open the lid, pressure is applied, preferably, at the bottom edge, raising the lid, the elongated bearing-slots permitting this, and when the lid is so raised the free end of spring O has passed the meeting point of the inclined faces 0.2 and a3 and occupies a position on the upper face a2, tending to throw the lid outwardly. The pintle now being opposite the enlargement or socket of the lower end of the bearing permits the lid to bodily move outward, and in such outward position the flanges b2 are out of coperative position with respect to the flanges a4 and the free end of spring C is resting upon the nose of the hinge lug, so that when the lid is turned on its pivot upwardly it will occupy IOO the position shown in Fig. 3. From this position it can be raised until the spring C rests upon the horizontal face a. to expose the opening in the journal-box for the purpose of giving full access thereto.

In closing lthe lid it is turned down until its inner face rests upon the flanges a4. From this position it is forced downwardly, so that its anges b2 engage the flanges 0.4 to lock the lid in place, and the hood-flange b3 coperaties with the inclined bottom wall a5 of the box. The pintle now occupies the upper narrow portion of the elongated bearing-slots, and the free end of spring C is resting upon the inclined face CL3 and exerts a constant downward pressure on the lid, holding it in its home position.

I am aware that many minor changes in the arrangement, construction, and combination of the several parts of my device can be made and substituted for those herein shown and described Without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The combination with ajournal-boxhaving a hinge-lug provided with three faces arranged at an angle to each other for coperating with the lid-spring, ofa lid, and a spring oh said lid, said spring bearing upon one of said hinge-lug faces to hold the lid in its home position, on another of said hinge-lng faces for holding the lid in a partially-open position, and on another of said hinge-lug faces for holding the lid in its full-open position; substantially as described.

2. The combination with a journal-box provided with a hinge-lug and pintle, of a lid having an elongated bearing,said bearing extending in the plane of the body portion and being enlarged at its lower portion for coperating withsaid pintle, and a spring on the lid for coperating with the hinge-lug for forcing said lid to, and holding said lid in, its home position; substantially as described.

3. The combination with a j ournal-box provided with flanges diverging from the point of support of the lid, of a lid provided with lianges diverging from its point of' support for cooperating with the boxtianges; substantially as described.

4. The combination with ajournal-box provided With diverging flanges, of a lid having a variable pivot-point, and flanges on said lid for cooperating with the box-flange; substantially as described.

5. The combination with a journal-box, of a hinge-lug and pintle, flanges on the box which converge toward said hinge-lug, a lid having an elongated bearing cooperating with the pintle, flanges on said lid for coperating with the box-flanges, and a spring on the lid for cooperating with the hinge-lug; substantially as described.

6. The combination with a journal-box provided with converging iianges a4, and a pivoted lid provided with flanges b2 and b3; substantially as described.

7. The combination with a journal-box, of diverging iianges thereon, a lid provided with diverging flanges for cooperating with said first-mentioned flanges for locking said lid in its home position on the journal-box, a spring which exerts a pressure to constantly hold said lid in its locked position, a pintle forming the pivotal point of said lid, said lid being provided with bearing-openings for engaging said pintle, whereby, when said lid is moved bodily it is unlocked from the box and the spring exerts a pressure to throw the lid open; substantially as described.

8. The herein-described journal-box provided With a hinge-lug @having the inclined faces a2 and as, the flanges a4, and the inclined bottom walls d5; substantially as described.

9. The herein-described journaLboX lid, the same having flanges b2, and the hoodflange or rib b3; substantially as described.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 4th day of May, 1900.

GEORGE S. MARSHALL.
